Manufacturing method of hand mold base for double mold plastic glove production line

- Sep 09, 2020-

Background technique:


At present, the PVC, nitrile and latex two-hand mold production line uses the hand mold holders imported from Malaysia to close the bearing chamber, the height of the positioning block is small, and the two sets of bearings in the bearing chamber do not need clearance. There are several disadvantages:


(1) The bearing room is closed. During the production of gloves, if the bearing room is open, it will inevitably cause the gloves to be dirty. Because the gloves are mostly used in the medical and food industries, the dirty gloves are a major defect, so the current gloves The production line is made into a closed bearing room, which brings a serious problem. The bearing is enclosed in the bearing room, and lubrication becomes a big problem. Because there is no lubrication, the bearing can only be installed with oil once during installation. The operating environment of the hand mold base is relatively harsh. Generally, it runs for a long time in an oven above 200 degrees, which causes the bearing to be stuck due to high temperature. The service life is more than 8 months, which is a great deal for glove manufacturers. waste;


(2) The two sets of bearings are close together and there is no gap, because the hand mold seat is a cantilever structure after the hand mold is installed. Once the bearing clearance increases due to use and lubrication, the shaking of the hand mold on the hand mold seat will increase. It is easy to cause collisions between adjacent hand molds, and then break the gloves on the hand molds, resulting in waste products. These waste products are difficult to remove from the production line. If mixed with genuine products, they will cause serious quality accidents in the hands of customers.

Technical realization elements:


In order to overcome the shortcomings of the existing technical solutions, the present utility model provides a manual mold base for a double mold plastic glove production line, which increases the overall height of the bearing chamber and maintains a longer lubrication time, which can effectively solve the problems raised by the background art.


The technical solutions adopted by the utility model to solve its technical problems are:


A hand mold holder for a double-mold plastic glove production line includes an L-shaped curved arm with a sleeve on the top and a plate, the L-shaped curved arm is connected with a bearing chamber, the bearing chamber is connected to the plate through a mandrel, and the The mandrel passes through a positioning block provided on the top of the plate, the bottom of the bearing chamber is connected with a spring cover, and the shaft of the mandrel between the spring cover and the positioning block is covered with a spring, characterized in that: the bearing A mandrel is axially installed inside the chamber through two bearings, and a spacer is arranged between the two bearings, a cross-shaped inner through hole is arranged inside the top of the mandrel, and the top of the inner through hole extends The top wall of the bearing chamber opposite to the inner through hole is provided with an oil hole.


Compared with the prior art, the beneficial effects of the utility model are:


(1) The utility model processes an oil filling hole in the closed bearing chamber, and then drills a hole on the shaft of the hand mold base to form an oil passage, which not only ensures that the bearing chamber is basically closed, does not stain gloves during production, but also enables The bearings are lubricated in time.


(2) The utility model increases the height of the bearing chamber, and adds a spacer between the two sets of bearings. The height of the spacer should be 15-20 mm. After improvement, the same bearing clearance will cause bumps at the hand mold. Greatly reduced, increased the rate of genuine gloves, and reduced the proportion of waste products entering genuine products.

Technical characteristics:


1. A hand mold holder for a double-mold plastic glove production line, comprising an L-shaped bent arm with a sleeve on the top and a plate, the L-shaped bent arm is connected with a bearing chamber, and the bearing chamber is connected to the plate through a mandrel, and The mandrel passes through a positioning block provided on the top of the plate, the bottom of the bearing chamber is connected with a spring cover, and the shaft of the mandrel between the spring cover and the positioning block is covered with a spring, which is characterized in that: A mandrel is axially installed in the bearing chamber through two bearings, and a spacer is arranged between the two bearings, a cross-shaped inner through hole is arranged inside the top of the mandrel, and the inner through hole The top extends to the top of the mandrel, and the top wall of the bearing chamber opposite to the inner through hole is provided with an oil hole.


2. The hand mold holder for a dual-mold plastic glove production line according to claim 1, wherein the spring cover is sleeved on the mandrel, and the top of the spring cover is provided with a retaining spring for a hole, and the hole is used for A circlip for shaft is arranged between the circlip and the inner wall of the bearing.


3. The hand mold holder for a dual-mold plastic glove production line according to claim 1, wherein a reinforcing plate is installed at the joint between the mandrel and the plate, and the joint between the mandrel and the plate passes through the pressure plate. Fixed installation together.


4. The hand mold holder for a double-molded plastic glove production line according to claim 1, wherein the height of the spacer is between 15mm-20mm.


5. The hand mold holder for a dual-mold plastic glove production line according to claim 1, wherein the transverse hole of the inner through hole penetrates to the surface of the mandrel.
